Description
Die Erfindung betrifft einen Zylinderkopf für eine direkteinspritzende Brennkraftmaschine, der eine zwischen zwei Nockenwellen stehend angeordnete Kraftstoffeinspritzdüse aufweist, mit einer Zylinderkopfhaube, die eine Durchtrittsöffnung zum Einsetzen der Kraftstoffeinspritzdüse umfaßt, einem bodenseitigen Sitz für die Kraftstoffeinspritzdüse und einer sich von der Durchtrittsöffnung bis zum Zylinderkopfboden erstreckenden, die Kraftstoffeinspritzdüse umschließenden Dichthülse.The invention relates to a cylinder head for a direct injection internal combustion engine having a fuel injector disposed between two camshafts, comprising a cylinder head cover having a fuel injection nozzle entry port, a fuel injector bottom seat, and a passage extending from the passage to the cylinder head floor. the fuel injection nozzle enclosing sealing sleeve.

Der Erfindung liegt die Aufgabe zugrunde, einen Zylinderkopf für eine direkteinspritzende Brennkraftmaschine der eingangs genannten Art zu schaffen, der eine platzsparende, einfache und wartungsfreundliche Befestigung der Kraftstoffeinspritzdüse ermöglicht und gleichzeitig den Ölkreislauf gegen Kraftstoffverunreinigungen schützt.The invention has for its object to provide a cylinder head for a direct-injection internal combustion engine of the type mentioned above, which allows a space-saving, simple and easy maintenance mounting of the fuel injector while protecting the oil circuit against fuel contamination.
Diese Aufgabe wird durch einen Zylinderkopf der vorgenannten Art gelöst, bei welchem ein Zwischenträger vorgesehen ist, die Dichthülse in den Zwischenträger eingepaßt und im Zwischenträger geführt ist, und auf der Zylinderkopfhaube benachbart zur Durchtrittsöffnung eine Spannpratzenaufnahme und eine Abstützfläche für ein Ende einer Spannpratze vorgesehen sind.This object is achieved by a cylinder head of the aforementioned type, in which an intermediate carrier is provided, the sealing sleeve is fitted in the intermediate carrier and guided in the intermediate carrier, and on the cylinder head cover adjacent to the passage opening a Spannpratzenaufnahme and a support surface are provided for one end of a clamping claw.
Hierbei ist eine Kraftstoffeinspritzdüse in die fest in den Zylinderkopf eingebaute Dichthülse einsteck- und über eine Spannpratze mit der Dichthülse verspannbar. Beim Ein- oder Ausbau der Kraftstoffeinspritzdüse liegen weder Teile des Zylinderkopfes frei, noch muß dieser hierfür geöffnet werden. Es ergibt sich ein erheblich verringerter Wartungsaufwand.Here, a fuel injector in the fixedly installed in the cylinder head sealing sleeve and can be clamped by a clamping claw with the sealing sleeve. When installing or removing the fuel injector neither parts of the cylinder head are free, nor must it be opened for this purpose. This results in a significantly reduced maintenance.
Zudem ist der Ölkreislauf durch die Dichthülsen gegen Kraftstoffverunreinigungen geschützt. Bei Undichtigkeit der Kraftstoffeinspritzdüse wird der Kraftstoff über die Dichthülsen zur Zylinderkopfhaube abgeführt, wo er ablaufen kann, ohne in den Zylinderkopf einzudringen.In addition, the oil circuit is protected by the sealing sleeves against fuel contamination. If the fuel injector leaks The fuel is discharged via the sealing sleeves to the cylinder head cover, where it can drain without penetrating into the cylinder head.
In einer Ausführungsform wird die Spannpratze durch eine Hutmutter gespannt. Zum Ausbau der Kraftstoffeinspritzdüse ist daher lediglich eine Schraubverbindung zu lösen.In one embodiment, the clamping claw is tensioned by a cap nut. To remove the fuel injector therefore only a screw is to be solved.
Es ist ein Zwischenträger vorgesehen, der sowohl mit der Zylinderkopfhaube als auch mit dem Zylinderkopf verbunden sein kann. Die Dichthülsen sind zweckmäßigerweise nur durch den Zwischenträger geführt, so daß die Zylinderkopfhaube beispielsweise für Wartungsarbeiten an anderen Teilen im Inneren des Zylinderkopfs problemlos abgenommen werden kann und lediglich Durchtrittsöffnungen für die Kraftstoffeinspritzdüse aufweist. Vorzugsweise sind Durchtrittsöffnungen im Zwischenträger abgeschrägt, um einen Dichtring oder dgl. einsetzen zu können, der sowohl gegenüber der Dichthülse als auch gegenüber der Zylinderkopfhaube abdichtet.An intermediate carrier is provided which can be connected to both the cylinder head cover and the cylinder head. The sealing sleeves are suitably guided only by the intermediate carrier, so that the cylinder head cover can be easily removed, for example, for maintenance of other parts in the interior of the cylinder head and only has passage openings for the fuel injector. Preferably, passage openings in the intermediate carrier are chamfered in order to use a sealing ring or the like, which seals both against the sealing sleeve and against the cylinder head cover.
Die Kraftstoffeinspritzdüse weist zweckmäßigerweise eine umlaufende Schulter auf, auf welche ein beispielsweise gabelförmiges Ende der Spannpratze aufsetzbar ist, um beim Festspannen eine in Richtung auf den Zylinderkopfboden wirkende Kraft auf die Kraftstoffeinspritzdüse auszuüben. Alternativ hierzu können beispielsweise zwei seitliche Schultern oder Taschen vorgesehen sein.The fuel injection nozzle expediently has a circumferential shoulder on which an, for example, fork-shaped end of the clamping claw can be placed in order to exert a force acting in the direction of the cylinder head floor on the fuel injection nozzle during clamping. Alternatively, for example, two lateral shoulders or pockets may be provided.

Durch die Dichthülsen 6 bilden sich von der Zylinderkopfhaube 2 durch den Zylinderkopf 1 bis zum Zylinderkopfboden 3 erstreckende, gegenüber dem Zylinderkopfinneren abgedichtete Kanäle. Hierzu können die Dichthülsen 6 wie dargestellt in einem Sitz 7 im Zylinderkopfboden 3 abdichtend befestigt sein und sich durch den Zylinderkopf 1 bis zu Durchtrittsöffnungen 8 für die Kraftstoffeinspritzdüsen 5 in der Zylinderkopfhaube 2 erstrecken. Dort sind sie mit der Zylinderkopfhaube 2 oder gegebenenfalls mit einem Zwischenträger 9 kraft- oder formschlüssig verbunden. Hierbei weist eine Durchtrittsöffnung des Zwischenträgers 9 zweckmäßigerweise eine Abschrägung 10 auf, in welche ein Dichtring eingesetzt ist, um den Zwischenträger 9 gegenüber der Zylinderkopfhaube 2 und der Dichthülse 6 abzudichten. Der dargestellte Zwischenträger 9 ist sowohl mit der Zylinderkopfhaube 2 als auch mit dem Zylinderkopf 1 verschraubt.Through the sealing

Ein Ende 17 der Spannpratze 13 stützt sich auf einer Abstützfläche 18 auf der Zylinderkopfhaube 2 ab. Ein weiteres Ende 19 ist mit der Kraftstoffeinspritzdüse 5 derart in Eingriff, daß es beim Festdrehen der Hutmutter 15 eine auf den Zylinderkopfboden 3 gerichtete Kraft auf die Kraftstoffeinspritzdüse 5 ausüben kann. Hierzu kann das Ende 19 gabelförmig die Kraftstoffeinspritzdüse 5 umgreifen und auf eine nicht dargestellte, vorzugsweise umlaufende Schulter am freien Ende der Kraftstoffeinspritzdüse 5 drücken. In weiteren Ausgestaltungen sind anstelle der Schulter zwei Auflagen oder Taschen 20 oder dgl. vorgesehen, vgl.
